How this calculator works
The Distance Between Points Calculator finds the horizontal change, vertical change, and straight-line distance between two coordinate points on a plane. Enter x1, y1, and x2 to estimate delta x, delta y, and distance. The calculator updates instantly and adds a comparison table plus chart so you can test the sensitivity of the result before you use it in a decision.

Inputs
- X-coordinate of the first point.
- Y-coordinate of the first point.
- X-coordinate of the second point.
- Y-coordinate of the second point.
Outputs
- Horizontal difference between the two points.
- Vertical difference between the two points.
- Straight-line distance between the two coordinates.
Assumptions
- The points are placed on a flat two-dimensional coordinate plane.
- Distance is measured as straight-line Euclidean distance.
Tips
- Check the coordinate signs carefully before interpreting the distance.
- Delta values can be negative even when the final distance is positive.

The straight-line formula is standard in geometry, but keeping the signed deltas visible helps when you also need direction or slope.
Distance by second X coordinate
| X2 | Delta X | Distance |
|---|---|---|
| 7 | 5 | 7.81 |
| 9 | 7 | 9.22 |
| 11 | 9 | 10.82 |
| 13 | 11 | 12.53 |
| 15 | 13 | 14.32 |
Holding the other coordinates fixed makes it easy to see how a moving endpoint changes the straight-line distance.
